I like the designe, the precission of the game feels nice, but i dont have any feel how much munition or granades or else i have. Needs maybe doomlike a better UI Colorsetting or some else. And some time a feel the creatures spawn behind me and i have no change to hear it before.
And last but not least: would be nice to have (doomlike too :) ) at the end of the level some statistics, like how many creatures killed, secrets, liters of blood usw.

Thx :)
